DISPLACEMENT MEASURING DEVICE, DISPLACEMENT MEASURING METHOD AND TENSION CONTROL CHART PREPARING METHOD
To provide a displacement measuring device capable of accurately measuring the displacement amount of a tendon end when introducing a tensioning force to the tendon.SOLUTION: A displacement measuring device measures the displacement amount of a tendon applying a compression force to a concrete structure, and has: a reflection plate member having a reflection plate and a fitting tool fitting the reflection plate to the tendon or to the piston of a jack pulling the tendon; and a laser displacement gage having a light projection part projecting laser beam to the reflection plate member and a light receiving part receiving the reflection light from the reflection plate member.SELECTED DRAWING: Figure 4
【課題】緊張材に緊張力を導入した際の緊張端の変位量を精度よく測定できる変位測定装置を提供する。【解決手段】コンクリート構造物に圧縮力を加える緊張材の変位量を測定する変位測定装置であって、反射板と、前記反射板を前記緊張材または前記緊張材を牽引するジャッキのピストンに取付ける取付治具とを備える反射板部材と、前記反射板部材にレーザー光を投光する投光部と、前記反射板部材からの反射光を受光する受光部とを備えるレーザー変位計と、を有する変位測定装置。【選択図】 図４
